Products Description
IEC 60695-11-5 Needle-flame Testing Method Small Flame Simulation Fire Hazad Test Appratus
Overview:
This needle flame test is used to simulate the effect of small flames that may arise in malfunctioning electrical equipment.
The burner which produces the 12 mm high test flame shall consist of a tube at least 35 mm long with a bore of 0.5mm±0.1mm and outer diameter not exceeding 0.9mm. The burner is supplied with butane or propane gas having a purity of at least 95%. There shall be no air admitted to the burner tube. To evaluate the possibility of spread of fire, for example by burning or glowing particles falling from the test specimen, a layer of the material or components normally surrounding or situated underneath the test specimen and the surrounding material or components when the test specimen is mounted as in normal use.
The test flame is positioned so that the tip of the flame is in contact with the surface of the test specimen. The test flame is removed after the specified time.
If the test specimen drips molten or having flaming material during the application of the flame, the burner may be tilted up to 45°from the vertical to prevent material from dripping into the burner tube while maintaining an 8mm±1mm spacing between the centre of the top of the burner and the remaining portion of the test specimen, ignoring any strings or molten material.
